I spend a lot of time on YT, and less time on Instagram... and 0 time on TikTok, where I never created an account.

YT Shorts exist exclusively for YT creators who want to publish bite-sized pieces of content for their audience with a much lower expectation of polish than their normal longer form content. Perhaps the algorithm also presents "random" YouTubers', too, but the vast majority of what I see is put out by the publishers I'm already following (or other very similar publishers in the same ecosystem).

I would suggest that TikTok's successor is Insta Reels. Reels are almost exclusively entertainment and because they tie into Instagram's broader user/connections network the UX is much better than TikTok. Nobody goes to Instagram to figure out how to replace their garbage disposal -- this is squarely YT domain. If YT Shorts can make inroads in the entertainment market [without feeling like a commercial break between pieces of actual content, which is the impression I have and the way I use it].
